To all whom it may concern:

Be .it known that I, WILLIAM C. Fir cx, acitizen of the United i States, residing at Deal Beach, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements inAp'par'atus for Welding Tubing, of which the fo lowing is a specification.

This invention relates to improvements in novel apparatus for use in electrically welding pipe and the object of the invention isto provide mechanism which will. make it possible to positively feed the. material through rollers while the material .is being heated to .weldingheat and also to provide means whereby art; of the mechanism may be shifted to ma e .the work operated upon accessible. f

In the preferable embodiment of my invention I employ afiied table which is pref erably water ceoled and carries a series of positively driven forming rolls, coactingj with which isa movable frame carrying a' table also water cooled). and positively driven rolls which coact with the rollers upon the fixed frame. This preferable embodiment is shown in the accompanying drawings and will now be described. I p

In the drawings accompanying and.form-.- ing part hereof, Figure .1 is an end elevation of mechanism constructed accordance with my invention. Fig. 2 is a viewof the ear-i ing used in Fig. 1. Fig. 3 is a side .e evetion looking from the right as shown in F ii. 1. I

eferring now to the details, of the draw= ings by numerals; 1 designatesthe main frame which is suitably connected to a bed or table 2 and which is provided with stand ards 3 whichisupport a table 1. The standards 3 also are provided with lugs 8 at one side which .form parts of ahinge; the other part-of thehinge being formed IZiPOD' a movable frame 10 .pivotallyconnecte to' the lugs 8 bymeansof a bolt12, the con-; strnctiombeing such that the movable frame 10 may be moved on the pivot 12 and'at the same time'the hin geis so constructed as to 1 form .a good electrical connection between the movable frame 110; and the main frame. 1;

. -I-norder to supply current to the main frame .1; 1 and itseonnected parts said frame is provided'rwith the usual bus-bars. 14 shown at ngwitli ers '3Farranged inthe position shown in -Figs. Land 3 and which are each supported this she 52 which ineshes with b and drives a similar .gensi securedto the sa ine shaft to which the left hand side of Fig. 1. The movable frame 10 is provided Wlth a lug 16 with wh ch coacts a pivoted latch 18 supported 2y one of thestandards 3 as clearl seen in 1g. 1 The construction is such" at when the pivoted latch 18 engages the lug 16 as shown in full lines in said Fig. l, the movable frame 10 is held in ope'rati've position with respect to the main frame. 1, and when it is desired to shift the movable frame 10, for the urpose of getting at thep'ipe being operate upon, all that itis necessary t'odo is to move the latch 18 when the operator may by engaging the handle 20, shiftflthe movable frame from the position shown in full lines in Fi 1 to the position shown in dotted line in t e'sarne fi ure, or farther if it is necessary to do so. e movable'fraine 10 also carries a table 22 coresponding to the aforesaid table 4 which-is carried by the,

main frame 1 and each of these tables is provided with connections 21 and 26 f01' supplying water for the purpose of reventin the tables from be comingtoo higlily heate when in use. Each ofthe tables 4 and 22 is provided with a series] of electrically-connected 'roov'edrollers 30 and 31 and coach these series is a set of vertical rollupon a shaft 38 $11 I orted by an arm 40 as .shown in Fig. 1.

n the operation of my idevioe the 'electric current passes from the roller" 36 throu h the pipe being operated.

P011 M r 30 -m but inasmuch as I am not claiming aspart of my inven tionfthe means of supplyingcurrent to these rollers it is i nnecessary to furtherfdescribe this feature.

Underneath each of the tablesi l' and 92 are a. series ofQgears 40, 41 and 12, these gearsjibeing connected with the, rollers 30 endlgl soas topositively drive the same. Bflween thejgearsO, 41 and 42 are idler ears 43 and 15. In order to drive these gears to positively rotate the rollers 30 and 31,1 em loy. a main or drive shaft 50 and fl? has connected to'it a. bevel gear one of the ars 42 is connected. The shaftmovable other than being rotatable. Se-

cured to the same shaft which carries-the bevel gear 54 is a gear 56 which meshes with a similar gear 58 on the shaft which carries the companion gear 42 on the movable frame 10. This construction makes it possible when the parts are as shown in full lines in Fig. 1 for the main shaft to drive all of the gears shown in Fig. 2. \Vhen thus driven, the metal forming the tubing, is positively fed throu h the rollers 30 and 31 and during this fee ing, the electric current is supplied through the rollers 36 so as to weld the pipe in its passage through the aforesaid rollers 30 and 31. It frequently becomes necessary to give some attention to the material in its passage through the rollers and for this purpose I have provided the movable frame 10 carrying the gears and rollers 31 so that this entire half of the. apparatus may be thrown to the position shown in dotted lines in Fig. 1 in order that proper attention may be given to the material when necessary.

From the foregoing and accompanying drawings it will be seen that I have provided mechanism for holding the tube in its passage through the welding apparatus which comprises two tables, preferably water jacketed, one fixed and the other movable, each of which carries a series of rollers and gears for operatin the same. It will also be seen that by simply releasing the latch 18 and moving the handle I the mov able frame 10. its table 22 and all of its gears and rollers may be moved away from the fixed table 1 and its connected gears and rollers. In operation a number of these tables is used, but as' they are usually identical, only one of them is shown in the drawings. I have referred to the fact that electric current may be used for the welding, which current may pass from the roller 36, through the metal being treated, to the rollers 30 and 31, but since my present in-' vention does not reside in the manner in which the current is caused to pass. I do not limit my claims to the particular manner in which the welding current employed.

, and means for positively driving said rollers said rollers being electrically connected, sub stantially as described.
